Disclosed are soluble diarylmethanofullerene derivatives that are effective as acceptors for organic thin-film solar batteries. They help to constitute effective organic thin-film solar batteries.
Phthalocyanine-C60 dyad 1 via a flexible saturated carbon linker was synthesized. The UV/Vis and fluorescence spectra studies of 1 revealed that intramolecular, not intermolecular, photoinduced electronic communication was observed in the solution state. We also examined UV-Vis and fluorescence spectra of a mixture of CM and conventional tetra tert-Bu phthalocyanine 2 for comparison
